Passkeys Explained: The End of Passwords (sentientrant.com)

Passkeys are built on the FIDO2 standard (CTAP2 + WebAuthn standards). They remove the shared secret, stop phishing at the source, and make credential-stuffing useless.

But adoption is still low, and interoperability between Apple, Google, and Microsoft isn’t seamless.

I broke down how passkeys work, their strengths, and what’s still missing

I think they are being pushed because cool technology on paper. Whenever I read an article about them, I can't help but think about the human factors. How are passkeys created, often by a password or email. okay... that looks a lot like a password. Oh you lost the passkey, here lets send you one again. It stinks of a second factor without a first. Sure, the passkey itself is hard to compromise, but how about its creation. If your email is compromised I see no difference from passwords or passkeys.

They don’t email you a passkey, what are you even talking about?

[–] l_b_i@pawb.social -4 points 5 days ago (1 children)

The flow I hear about when people talk about passkeys is sign up with email. Code gets sent to email. Code is entered, passkey gets generated. There always seems to be some similar step that looks like that, and often you have new device or reset that looks the same. Sure the passkey itself is secure, but how do you get it, how do you generate it, how do you validate the first time?

None of that is remotely true lol. You don’t get a passkey, you generate. Nothing is “sent” to you at any point in time, it has nothing to do with email.

Instead of saying how it doesn't work, it'd be more constructive to explain how it does.

Seems a little redundant when the article we're all commenting on does precisely that.

You mean like… the article you’re commenting on does?
